16-bit DSC/MCUs have touch, analog, 70 MIPS

With op amps, PWMs, and a charge time
measurement unit peripheral (CTMU), the 16-bit dsPIC33 and PIC24EP
digital signal controller and microcontroller families enable
advanced features in user-interface, intelligent-sensing, and
motor-control applications at very low cost. The devices are pin
compatible with existing 16-bit dsPIC33 and PIC24 ICs and are
available in multiple packages, including a new 5 x 5-mm 36-pin
VTLA.

The chips feature 70 MIPS of DSP performance and
a 6-channel PWM peripheral. They provide advanced motor control and
their CTMU peripheral, used in capacitive touch-sensing, simplifies
the addition of innovative and reliable user interfaces, including
keypads, buttons, and sliders. They run from a 3.0 to 3.6-V supply
over –40º to 85ºC. (From $1.58
